The invention relates to a sowing machine (1, 31) and a method for separating and distributing granular material (2), such as seeds or similar, wherein the material is supplied from a central container (12) to metering devices (3) via respective conveying channels (11) assigned to same, by means of conveying air flows (10), and discharged from same. Resulting waste air flows (14) are supplied to the respective associated metering devices via waste air channels (15) and said metering devices are thereby applied with overpressure. In addition, the metering chambers are applied with overpressure via said respective assigned supply channels (8) by means of supply air flows (7). The material is separated in the metering chambers by means of separating discs (5). Given that the supply air flows and the waste air flows are physically separately introduced into the metering chambers, the required pressure level in the discharging devices (13) generating the waste air flows can be reduced and thereby also the pressure level in the granular material delivered to the metering devices from the discharging devices. This improves the separation quality of the metering devices.

Accordingly, a target throwing distance is determined for a target working width. One of a plurality of rotation speed levels is also selected for at least one spreading wheel so that the actual throwing distance approximates the target throwing distance. Finally, an adapted target throwing angle for regulating an actual throwing angle is determined from the actual throwing distance (WW1), said target throwing angle compensating for a deviation from the target working width caused by the difference between the actual throwing distance and the target throwing distance. Continuous regulation of the throwing distance thereby becomes unnecessary, resulting in more stable regulation of the throwing behaviour overall.

Disclosed is a seeder which has a large operating width and comprises a central frame (1) supported on the ground by trailing wheels (3). A middle frame that supports seeding shares is arranged on the central frame (1). Two side frames that are hinged together can pivot relative to one another about a pivot axis extending in the direction of travel (10) and are laterally hinged to the middle frame by link joints. At least one preferably radially non-symmetric storage container unit (4.1, 4.2) that includes at least two separate storage container zones (4.1.1, 4.1.2, 4.2.1, 4.2.2) is arranged on the central frame (1) behind the seeding shares, behind the middle frame and above the trailing wheels (3). In order to be able to easily increase the volume of material carried on the seeder having a large operating width, two storage container units (4.1, 4.2) are arranged directly behind one another.

The invention relates to a frame component for devices and machines, preferably agricultural devices and machines. In particular, the invention relates to a frame component for mounted tractor plows, trailer plows, and semi-mounted plows, comprising a hollow profiled body (1) which has an upper face, a lower face, and lateral faces and on which tools, tool supports, brackets, support wheels, and such attachment elements can be supported. The aim of the invention is to allow an individual design of a frame component with a simplified production but increased material properties. This is achieved in that the hollow profiled body (1) is made with at least two individual components (2, 3, 4) which are adhesively bonded to each other.

The invention relates to a seed drill coulter (1) for the direct seeding method, comprising a tear-open body (11) arranged on the side of the seed drill coulter (1) facing the driving direction (6) for tearing open the ground, wherein a tear-open tip (14) is arranged in the lower region (13) of the tear-open body (11), which tear-open tip is at least as narrow as the tear-open body (11) itself, wherein the bottom side (15) of the tear-open tip (14) extends upward and toward the rear, wherein the tear-open tip (14) has an armor (16, 17), which is arranged in the front, lower upright region (18) facing the driving direction (6) and on the underside (15) of the tear-open tip (11). According to the invention, in order to achieve an additional increase in the service life of the chisel sowing plough (11) for extreme locations of use, the armor (17) arranged on the underside (15) of the tear-open tip (14) is arranged at least in the rear region (19) of the underside of the tear-open tip (14).
